Perhaps you should try some spelling variations:
phuong cong » phuong dong, phong cong, phung cong
cua phuong » cuu phuong, cuc phuong, luan phuong
chieu sach » chinh sach, chiet tach, chieu sang
chuc danh » chuc nganh, thuc hanh, chuc nang
manh toan » thanh toan, anh tuan, tinh toan
anh tang » anh bang, anh dang, anh nang
tang cua » mang cua, hang cua, tang luan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chuc danh) OR (chieu sach)) - anh tang cua phuong cong ((dan toan) OR (manh toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chieu sach)) - anh tang cua phuong cong ((dan toan) or (manh toan)) cao*.
